To ALL wnoM Ir MAY' coNoEnN:

Be it known that I, ROLLIN S. EDDY, of La Crosse, in the county of LaCrosse, and State of Wisconsin, have invented certain new and useful Improvements in Horse-Powers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use my invention, I will proecedto describe it.

My invention relates to horse-powers, and consists of novel construction and arrangement of mechanical devices-for 'distributing and equalizing the strain' throughout the gearing, and by the use of which the power' may be easily taken apart for repairs or other purposes, and readily put together again. In the drawings- Figure 1 is a top plan View, with a portion ofthe support E broken away.

Figure 2 is a transversevertical section of fig. 1.

Figure 3 is a longitudinal section of apart, detached;and l Figures 4, 5, and 6 represent the application of my device to what are popularly known as the Pitts or Carey power and the Woodbury power.

I construct a strong, substantial frame,vA, and mountv therein the Atwo shafts B-B in suitable nearings, a a', and'so that they shall be in a straight line'with each other, as shown in iig. 1. To the shafts B B I key the bevel-gear'wheels C C', just within their outer bearings, and on their ends, which are immediately opposite each other, I key the spur-wheels G G', as shown in jrigs. 1 and 2. Across the middle of the frame A, I place a strong support, E, a little arched or circling, as shown in fig. 1, and with its legs rmly attached to the frame, and provided at its centre with'v an upright journal or pin, D, as lclearly shown in iig. 2. 0n the journal D, I place a driving-wheel, F, so as to move easily` about it. The driving-wheel F, I provide with bevel-gear on the under side of its periphery, and of the proper size to allow it to gear into the bevelwheels C C. Also, in the frame il, I mounts. smaller shaft, I, inbearings, d d, and to this shaft key two spur-pinions, ef, arranging them as shown in iig. 1, and so that the wheel G shall gear into the pinion e, and the pinionf into the spur-whee1 y.

v immediately under it.

Besides the shafts B," B', and I, the former of which are on a line with one another, and the latter parallel with them, `I mount in the frame A the line-shaft H, under the shaft I, and parallel with it, and on itiplace two so that the pinionf shall gear into the wheel g, and the wheel G into the wheel g. The collars z' are pinned to the shaft H by pin l, as shown in iig. 3.

On the inner opposing faces of the wheelsg g', I place 'bevehgearing 71. h, which may be a part ofthe wheels g g', or may be bevel-gear'wheelsrigidly attached, and on each end of a pin, m, passing through the shaft H, and rigidlyattached to it, and midway between th'e wheelsg g', I place the bevel-,wheels a n', so as to move loosely on the pin m, and gear into the bevel-gear L t, attached to the wheels gg. l

In operating my horsepower,it will be seen that the driving-wheel F, acting on the loose wheel g, the wheels C', G', e, and f, and on the wheel g through the wheels G and G, will cause th revolve in the same direction, and carry with them the wheels t and L, which in turn will carry with them the bevel-,wheels n and at', and thus turnl the line-shaftH as desired. -And as by this arrangement the wheels g g', and li t, and n ln', and the collars z, which hold the wheels g g in position, all move together in the same direction when the machine is in operation, very much of the friction and jar caused by the thrusting of the gearingare avoided and diminished. And in case any portion of the machine While running should be broken by accident or otherwise, so that the wheels g y should not or could not move evenly together, the bevel-wheels n n will at once adapt them to every change they may make, and thus equalize their unevenmovements, if any.

In the drawings I have shown the application of my devices in what is popularly known as the climax- *through e wheels g and g to` mns 2 power, but I also apply it with similar advantages in what is known as the"Pit-ts o1CnreyandtheWoodr i bury power, as shown in igs.4,' 5, and 6.

My'device, as applied to the Woodbury mounted power, for distributing and equalizing the strain throughout the gearing, is shown in figs. 4 and 5. In iig. 4, Nis the open ring or master-wheel, having no arms, but

being simply a ring with teeth on the to-p and bottom sides, which mesh into pinions, P Pf, one in the top, and the other in the-bot`toni of the wheel N, and cause the shafts L and L', to which these pinions are attached, to move with eqal velocity in the same direction, as denoted by the red arrows on the pinions P P. lThe bevel wheels h L, in this case, are keyed fast to the shafts L L respectively. The bevel-wheels n n run upon projeetions cast upon the spurwheel N, or any equivalent of the same, instead of upon a pin passing through the line-shaft, as in iigs. 1, 2, and 3. The spur-wheel N runs loosely on the shaft L, and the wheels n" and n also run loosely on their bearings. The whole are held in place by a head or collar at M, which serves the same purpose that collars z'z do in figs. 1, 2,- and 8. l

In operating this power with my device thus applied, I give motion to the master-wheel N, which turns the pinions l? P' in the direction shown by the red arrows, with their shafts L L', and which in turn give motion to the spur-wheel N through the wheels t 7L and n at. It will thus be seen that if from any causo either of the` pinionsl or P should be inclined to receive the hardest strain of the wheels 7L and iturning independent of' the shafts L and L', the strain through the wheels l1, it'. and n n will he equally distributed or divided to every wheel in the power, as in the arrangement Erst described.

The manner of applying my device to the Pitts or Carey power, popularly so termed, is clearly shown in iig. 6, in whichthe beve1-wheels 7L i turn loosely on the line-shaft H, and are connected with and revolved by the bevel-wheels g g', the bevel-wheel g being moved by the bevel-wheel R, and the bevel-wheel y by the bevel-wheel R. The whole are held in by a collar at M. Ey this arrangement, as in those above describerh, the strain is equalized andA distributed evenly in the gear of the power.

In thesemodieations, shown in gs. 4, 5, and 6, it is obvious that my device will distribute and equalize the strain on the gear, diminish the friction and jar caused by the thrusting of the gearing asl eiectually as in what is popularly described and known as the climax-power, rst above particularly set forth.

Having thus described my invention, 'what I claim, is l 1. In a horse-power, the bevel-wheels t 7L and n n', or their equivalents, when constructed and arranged as described, for the purpose of distributing and'equalizing the strain throughout the gearing. l

2. The piu m, and collars z', or their equivalents, when` constructed and arranged substantially as herein describecLand for the purpose set forth.

3. The wheels h 7L and 'n a, arranged as herein described, on a shaft, II,-and held in place by a collar on the shaft, in combination with the shaft or with a master-wheel, N, in a horse-power, substantially as described, and for the purpose set forth.

4. The use cfa device for equalizing the strain in horse-powers, consisting ot' two bevehwheels, L zf, or their equivalents, arranged to run loose on ashaft, H, and in tho same direction, and to mesh into two other corresponding bevel-wheels, n n, or their equivalent, running loose on a pin, M, at right angles with the shaft H, and attached toit, as shown in figs. 2, 3, and G, or to bearings on a wheel, N, turning about a shaft, lL, as shown in figs. 4 and 5, the whole being held in place by collars on said shafts, or their equivalents, and constructed and arranged to operate substantially-as described.
